The effects of gravity on near-surface objects and those in Earth orbit are explored in this activity. A brief explanation, links to three related videos, a teacher's guide and short assessment are included.

Become a crime scene investigator! Learners model Dawn Mission scientists, engineers, and technologists and how they use instrumentation to detect distant worlds. After a briefing to build context, students explore interactions between different...(View More) frequencies/wavelengths of the electromagnetic spectrum and matter as they investigate the different ways scientists gather and understand remote sensing data, using Dawn instruments as examples. This module is organized around a learning cycle, engaging students through several experiences to activate students' prior knowledge and assess conceptual understanding, informing next steps.(View Less)

This slide set focuses on the discovery of an intermediate mass black hole in M83. It is one of a series of short, topical presentations on new developments from NASA astrophysics missions, relevant to introductory astronomy topics. These resources...(View More) are intended to help instructors include the latest discoveries (not yet in their textbooks) into their courses. The slide sets are constructed to be easily included as a lecture supplement including synopsis, references, and graphics.(View Less)

This ChemMatters article provides a history of the study of ozone, a description of an experimental simulation called "The World Avoided," a brief introduction to the chemistry of ozone, an explanation of how ozone is measured, and the difference...(View More) between "good" ozone in the stratosphere vs "bad" ozone in the troposhere. ChemMatters is an educational magazine published by the American Chemical Society.(View Less)

This activity allows participants to build a paper model of the GPM Core Observatory and learn about the technology the satellite uses to measure precipitation from space. Directions explain how to cut, fold and glue the individual pieces together...(View More) to make the model. The accompanying information sheet has details about the systems in the satellite including the Dual-frequency Precipitation Radar (DPR), the GPM Microwave Imager (GMI), the High Gain Antenna, avionics and star trackers, propulsion system and solar array, as well as a math connection and additional engineering challenges.(View Less)

Students are introduced to the Global Precipitation Measurement (GPM) satellite mission and its role in studying the water cycle. This webquest provides links to eight websites, allowing middle school students to explore the water cycle and its...(View More) impacts on Earth's weather and climate. Through online videos and articles, students follow a water molecule through the cycle, discover the connection between the water cycle and global water/heat distribution, examine the role of solar energy, and assess the importance of fresh water.(View Less)

In this activity, students face an engineering challenge based on real-world applications. They are tasked with developing a tool they can use to measure the amount of rain that falls each day. Students will find out why freshwater is important,...(View More) learn about the water cycle, and the need to have a standard form of calibration for measurement tools. They will learn that keeping track of precipitation is important, and learn a little bit about how NASA's GPM satellite measures precipitation from space. This lesson uses the 5-E instructional model.(View Less)

This lesson was developed to give participants an understanding of Earth's water cycle. In this one-hour long activity, students participate in a webquest to learn about the water cycle, and then build a mini-model of the water cycle to observe how...(View More) water moves through Earth's four systems. The activity uses the 5E instructional model and is part of the "Survivor Earth" series of one-hour lessons.(View Less)

In this activity, participants learn about the hydrosphere by making observations and taking measurements. They will go outside and use scientific equipment to investigate temperature, pH and transparency of a body of water. They will use this...(View More) qualitative and quantitative data to understand why it is important to know about the condition of freshwater sources in many places in the natural environment and how these places are connected in the water cycle. Data collection is based on protocols from The GLOBE Program. This activity uses the 5E instructional model and is part of the "Survivor Earth" series of one-hour lessons.(View Less)

This module focuses on ultraviolet radiation on Earth and in space and how it affects life. Learners will construct their own "martian" using craft materials and UV beads. They will explore how UV radiation from the Sun can affect living things,...(View More) comparing conditions on Earth and Mars, and then discuss ways in which organisms may protect themselves from UV radiation. They will then take part in a Mars Creature Challenge, where they will change their creature to help it survive harsh UV conditions — like on Mars. They will then test their Mars creatures by subjecting them to different environmental conditions to see how well they "survive" in a martian environment. This investigation will explore shelter and protection as one of life’s requirements and how Earth’s atmosphere protects life from harmful UV radiation. It also includes specific tips for effectively engaging girls in STEM. This is activity 5 in Explore: Life on Mars? that was developed specifically for use in libraries.(View Less)
